This guy happens to have access to a 6000x3000 pixel display and is using it to display extremely high resolution pictures of Ultima maps? I am impressed, but a bit perplexed. Maybe it's just because I'm not much of an RPG player, but I'm thinking Lost, Monday Night Football, Project Gotham 3.
The tech behind it was developed by those lovely folks who brought you the MP3, the Fraunhofer Institute. The purpose is to allow you to still see the picture perfectly and in high detail even when standing right next to it. The picture shown takes 48 projectors and 48 PC's to create the 18 megapixel image.
